Magnetek N-6U Stepdown Autoformer 230V to 115V 200VA 50-500Hz Single Phase

Magnetek N-6U Stepdown Autoformer 230V to 115V 200VA 50-500Hz Single Phase

The Magnetek N-6U is a single-phase stepdown autoformer designed to reduce a 230V AC supply to a 115V AC output at up to 200VA. Autotransformers of this type use a single shared winding rather than isolated primary and secondary windings, making them compact and efficient for straightforward voltage conversion applications. The N-6U is a chassis-mount open-frame unit with lead-wire connections and integrated mounting feet.

Applications

Stepdown autoformers like the Magnetek N-6U are used wherever equipment rated for 115V AC must be powered from a 230V supply — common in international equipment deployment, laboratory settings, light industrial environments, and situations where U.S.-spec devices are operated on 230V infrastructure. The wide frequency range of 50–500 Hz makes the N-6U suitable for use across different power grid frequencies, including both 50Hz and 60Hz mains, as well as some higher-frequency motor-drive and inverter outputs. Magnetek was a well-known U.S. manufacturer of transformers and power electronics; the company's transformer division was active from the late 1980s through the 1990s and supplied a broad range of standard and custom magnetic components to industrial and commercial customers.
